Answer :
The last great painter of the Byzantine era who discovered and mentored Giotto di Bondone was Cimabue. Cimabue was an Italian painter known for his influence on the transition from the Italo-Byzantine style to the early Italian Renaissance. He played a significant role in the development of Western art.
Cimabue's importance lies in his innovative approach to art and his mentorship of Giotto di Bondone, who is often regarded as the father of Western painting and a crucial figure in the development of the Renaissance. Giotto's style marked a departure from the flat and stylized Byzantine art towards a more naturalistic and expressive representation of the world.
In summary, Cimabue is considered the last great painter of the Byzantine era and a key figure in the evolution of Western art, particularly for his influence on Giotto di Bondone.
